java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String; while using PhantomJS 2.1.1 with Selenium

Question

OS - Windows 7

PhantomJS version - 2.1.1

Selenium - 3.8.1(selenium-server).

JDK - 152.

I\'m trying to run simple test, using PhantomJS:

Answer 1

Just to add a different scenario where the same exception can be faced.

While using Eclipse below code was working :

File file = new File("C://phantomjs.exe");
System.setProperty("phantomjs.binary.path", file.getAbsolutePath());
WebDriver driver = new PhantomJSDriver();

While using Intellij, the same above code was throwing the error as mentioned in the question.

But the below worked with the Intellij :

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "C:\\phantomjs.exe");

WebDriver driver = new PhantomJSDriver(capabilities);

Note:Dont forget to change the exe path.

Answer 2

The error you are seeing says it all :

NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String;

Class NoSuchMethodError

NoSuchMethodError extends IncompatibleClassChangeError and as per the Java Docs it is thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method. Normally, this error is caught by the compiler and this error can only occur at run time if the definition of a class has incompatibly changed.

Solution

Perform the following steps :

• Update your JDK to the most recent versions (Java 8 Update 151)
• Clean up the Project Space from the IDE.
• Run CCleaner tool to wipe off all the OS system chores.
• Take a System Reboot
• Add only Selenium-Java Clients v3.8.1 jar.

• As you are using PhantomJSDriver (GhostDriver) you need to add the following Maven Dependency :

  <dependency>
      <groupId>com.github.detro</groupId>
      <artifactId>phantomjsdriver</artifactId>
      <version>1.4.0</version>
  </dependency> 
  

• You need to update the line System.setProperty with the absolute path of the phantomjs binary as follows :

  File path=new File("C:\\path\\\to\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
  System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
  WebDriver driver= new PhantomJSDriver();
  driver.navigate().to("https://www.google.co.in/");
  

• Execute your Test
